Hi C.,
I'm a child care provider and I love working (playing) with the big blocks. Here's a really inexpensive way that I went about furnishing my latest set of big cardboard blocks. I asked my child care clients to bring in all of their empty really colorful CapriSun juice boxes. They are about the same size as the store bought stackable boxes, are colorful, and the children love playing with them. Each box was opened on just one end to remove the juices, so when I got the boxes I taped that end shut with duct tape or packing tape. I'm into having fun, but I'm also into saving a few bucks. I hope this helps.
